Title: Heat accumulator of bath
Inventor: KURITA YUKIO
IPC: F24H7/02
Filed: 1983-02-28
Abstract: PURPOSE:To remarkably reduce the dissipation of heat of the hot water spent for bathing by a constitution wherein the hot water in a bathtub is heat-exchanged with the cold water in a heat storage tank covered with heat insulating material by means of the natural circulation of said hot water in the bathtub in order to store the heat of the hot water in the bathtub in the cold water in the heat storage tank so as to be able to supply the resultant hot water in the heat storage tank to the bathtub and other side when necessary. CONSTITUTION:A bath is of a circulating type that a bathtub 1 communicates through an upper and a lower circulating pipes 2 and 3, in which valves D and E are arranged respectively, to a bath heater 5 installed outside a partition wall 4. A heat storage tank 7, the periphery of which is covered with heat insulating material 6, is installed so that the bottom of the tank 7 is located higher than the liquid level in the bathtub 1. After bathing, valves B, C, D, and E are closed and a valve A is open in order to feed water through a feed water pipe 10 to the heat storage tank 7. When the valve A is closed and the valves B and C are open after the tank 7 is full of water, the hot water in the bathtub 1 and the cold water in the heat storage tank 7 are heat-exchanged with each other due to the natural circulation of the hot water in the bathtub 1 developed by the difference between the temperature of the hot water in the bathtub 1 and that of the cold water in the heat storage tank 7. As a result, the water in the heat storage tank 7 turns to be hot, while that in the bathtub 1 turns to be clod. After that, the valves B and C are closed. The hot water in the heat storage tank 7 is fully retained its temperature at the conditions just mentioned above with the heat insulating material 6.

Title: Semiconductor storage
Inventor: KOSHIDA HAJIME
IPC: G11C11/401
Filed: 1997-01-31
Abstract: PROBLEM TO BE SOLVED: To reduce a chip size by configuring a circuit where a write-selection signal being required for selecting a write switch is eliminated in the write- operation of a semiconductor storage such as a DRAM. SOLUTION: A write enable signal WE and a write data complementary signal WIT/WIN are inputted to a write switch output circuit WSS. Then, when a write data output circuit WBUF is inactive, write data complementary signals are both 'H', so that an NAND1 outputs 'L' and a write switch WSS outputs 'L'. When the write data output circuit WBUF is active, one of the write data complementary signals becomes 'L', so that the NAND1 outputs 'H'. When the WE signal becomes 'H', the output of the NAND2 becomes 'L', an inverter circuit INV is inverted and the switch signal WSW becomes 'H', namely ON state, so that the write switch is turned on only for a sensing amplifier part where write data are outputted.

Patent JP-H01209176-A (JP)
Title: Printer
Inventor: WADA SHUNEI
IPC: B41J29/50
Filed: 1988-02-18
Abstract: PURPOSE:To enable a reference position to be determined stably, by driving a carriage-moving means at a high speed in a switch-detecting direction, stopping the carriage-moving means upon detection by a contact-type switch mechanism, driving the carriage-moving means in the opposite direction until the detection by the switch mechanism is lost, and driving the carriage-moving means at an extremely low speed until detection by the switch mechanism. CONSTITUTION:When a contact-type switch 15 is ON, a carriage 1 is moved rightward by driving a carriage motor 10 until the switch 15 is turned OFF. When the switch 15 is OFF, the carriage motor 10 is operated at a speed V1 until the switch 15 is turned ON. Since the speed V1 is high, there is a possibility that the output position of an operation signal of the pulse motor 10 may be deviated from a reference position due to chattering of the switch 15. The carriage 1 is moved rightward, and the switch 15 is turned OFF. The carriage 1 is moved leftward at an extremely low velocity V2, and the position at which the switch 15 is turned ON is detected. The velocity V2 is so low that the switch 15 does not chatter, and the signal from the switch 15 is stable, so that an accurate reference position can be detected.

Title: Gettering of semiconductor substrate
Inventor: KOTANI TOSHIYUKI
IPC: H01L21/322
Filed: 1979-03-23
Abstract: PURPOSE:To accomplish the gettering of heavy metal with heavily strained layer produced on the boundary between two kinds of thin films varied in the coefficient of the heat expansion closely arranged on one surface of the semiconductor substrate. CONSTITUTION:A Si3N4 film 2 is formed on the surface not intended for formation of elements on the Si monocrystal plate by CVD method and an opening 3 is made thereon at a given space. Then, an SiO2 film 4 is made by wet oxidation. An element is formed on the main surface void of the film 2 on the substrate where a strained layer is formed. With such an arragnement, any strained layer can be reproduced easily through the oxidation process even when the strain is reduced due to the high temperature treatment in the production process. As the Si3N4 film and the SiO2 film provides individual tension and compression force against Si, proper selection of the pattern form and the film thickness allows the elimination of warping of the substrate. The combination of BSG with Si3N4, SiO2 or the like is possible.

Title: Perforated pipe for underground cable protection
Inventor: YAMAGUCHI MASAYASU
IPC: F16L9/08
Filed: 1995-01-31
Abstract: PURPOSE: To provide a lightweight perforated pipe for cable protection capable of reducing the frictional resistance when introducing a cable and having watertightness, by placing and securing a plurality of synthetic resin tubes the cross-sectional dimension of which allows a cable to be accommodated, in parallel in an inorganic solidifying body. CONSTITUTION: The same-side ends of a plurality of polyvinyl chloride cylindrical tubes are vertically inserted into the round hole in polyethylene plate, and placed on the bottom of a molding box. solidifying body material is poured into the molding box while avoiding its entry into the cylindrical tubes. When the solidifying body material is completely solidified, the molding box is removed. Thus, a perforated pipe is formed out of aerated concrete using fly ash with its internal cable placement hole made of polyvinyl chloride. Using synthetic resin for hole forming members with which cables will be brought into contact, as mentioned above, will reduce the frictional coefficient when a cable is introduced. This makes it possible to smoothly introduce cables into the holes, and provide the perforated pipe with watertightness.

Center dilocating signal that approaches another induction heater coil 1 to the problem position is inputted to D/A converter 6 at a time after the specified delay. The signal is converted to analog quantity and is compared with location signal of potentiometers 51, 52 of the servo amplifier 7. Output from the servo amplifier 7 controls coil energize circuit for solenoid switch valves 41, 42, so that the axis center of the coil 21 is located at the position indicated by the output from the calculator 12. Thus, peripherally uniform temperature is given to the steel tubing M.
